I cannot open SDL 2019 anymore ! - "Classe non valide" error message

Hi

I cannot open SDL anymore,

one of your colleague sent to me this article :the following article: https://gateway.rws.com/csm?id=kb_article_view&sysparm_article=KB0028332

I did steps 1 to 5. 

I did also root cause procedure and it seems that there is a MWI failure.

Please could you help me?

I feel unconfident to carry out the procude mentionned by microsoft.

As you can guess I really need to open my SDL 2019 to continue to work Slight smile

Thank you so much!
